Really simple callback to get logging for each tree Example usage: ```python import gym from stable_baselines3 import PPO from stable_baselines3.common.monitor import Monitor from stable_baselines3.common.vec_env import DummyVecEnv, VecVideoRecorder import wandb from wandb.integration.sb3 import WandbCallback config = { "policy_type": "MlpPolicy", "total_timesteps": 25000, "env_name": "CartPole-v1", } run = wandb.init( project="sb3", config=config, sync_tensorboard=True, # auto-upload sb3's tensorboard metrics monitor_gym=True, # auto-upload the videos of agents playing the game save_code=True, # optional ) def make_env(): env = gym.make(config["env_name"]) env = Monitor(env) # record stats such as returns return env env = DummyVecEnv([make_env]) env = VecVideoRecorder( env, "videos", record_video_trigger=lambda x: x % 2000 == 0, video_length=200 ) model = PPO(config["policy_type"], env, verbose=1, tensorboard_log=f"runs") model.learn( total_timesteps=config["total_timesteps"], callback=WandbCallback( model_save_path=f"models/{run.id}", gradient_save_freq=100, log="all", ), ) ``` N)LiteralOptional) BaseCallback) telemetryc s~eZdZdZ     ddedeededed eed d df fd d ZdddZ d e fddZ dddZ dddZ ZS) WandbCallbackaCallback for logging experiments to Weights and Biases. Log SB3 experiments to Weights and Biases - Added model tracking and uploading - Added complete hyperparameters recording - Added gradient logging - Note that `wandb.init(...)` must be called before the WandbCallback can be used. Args: verbose: The verbosity of sb3 output model_save_path: Path to the folder where the model will be saved, The default value is `None` so the model is not logged model_save_freq: Frequency to save the model gradient_save_freq: Frequency to log gradient. The default value is 0 so the gradients are not logged log: What to log.
